Background: The nasopalatine canal (NPC) is a long and thin intraosseous passage present in the anterior midline of the maxilla that connects the palate with the floor of the nasal cavity. The objective of the study was to compare the measures of nasopalatine duct and its shape by cone beam tomography in dentate patients with respect to edentulous patients in the frontal anterior sector. Materials and methods: descriptive and comparative study, was taken from the files of the Imagenology Department 150 tomographies of anterosuperior dentate patients and 52 tomographies of edentulous in the frontal anterior sector. Unsing the Excel program and its tool “random”, 30 tomographies of dentate patients were selected as well as the 30 tomographies of edentulous. Were measured in the oblique sagittal plane the anteroposterior distance of the nasopalatine canal at the level of its upper, middle and lower third. To determine its height, the axial plane was taken from the level of the upper bifurcation to the palatal opening. The acquisition of images was done through the i-Dixel software of the 3D Accuitomo 170 MORITA, DICOM system. Results: the dentate patients present higher heights in relation to the edentulous patients. In edentulous patients the diameter have a larger size at the NPC channel level. The measurements at the lower, middle and upper levels in the cortices of the diameter of the NPC in dentate patients are lower in relation to the edentulous patients. Conclusion: Patients of 40 to 70 years old, male and female, with frontal anterior edentulism presented structural topographic variations that consist of greater width, smaller longitudinal dimension and larger transversal dimension being enlarged canals.
Análisis estético dentofacial: base de la terapéutica en deformidades faciales
(2018) Cazar Almache, Marcelo Enrique; Abril Cordero, Luz Marina; Recendez Santillán, Norith De jesús
The analysis and diagnosis of dentofacial alterations is the basis of the surgical orthodontic treatment of facial skullmass, facial deformities from a functional approach to a esthetics through clinical and technological tools such as imaging studies: cephalometric, cone beam tomography and stereolithographic models. The study of the facial aesthetics of the human being has been developed since antiquity based on the classic canons, which have marked as standard in the collective subconscious, the greek standards as the standard norm of facial beauty and that do not always coincide with all ethnic groups as in the case of Ecuadorian society. The present work intends to give to the student of pre and post of our means a methodology to approach the complexity of the aesthetic analysis dento facial coupling the classic interpretation to our multiculturalism.
Tumor pardo maxilar: reporte de caso
(2019) Abril Cordero, Luz Marina; Cazar Almache, Marcelo Enrique; Espinoza Soto, Pedro Esteban; Palacios Vivar, Diego Esteban; Cañar Rivera, Gabriela Elizabeth
Introduction: Brown tumor is a rare pathology resulting from uncontrolled hyperparathyroidism, which produces areas of localized bone destruction. They are present at the facial level in the mandible and maxilla, ribs, clavicle, pelvic waist and upper and lower extremities. Its name is given by the pigmentation of the extravasation of blood and hemosiderin to the tumor. It can manifest itself in any decade of life. Has greater predisposition in women of the fourth and fifth decade of life. Its presence at the level of maxillary bones requires a complex system of studies and multidisciplinary management for diagnostic confirmation and treatment. Clinical case: The case of a 36 year old patient with no personal or family history is reported. She comes by referral for placement of a bone graft for dental mobility. In the image evaluation, there is a right radiolucent zone in the body of the mandible, in relation to the teeth. The lesion usually presents as a well-delimited unilateral or multilocular radiolucent area; another important radiographic finding in hyperparathyroidism is the absence of hard laminae around the dental organs. Conclusions: The brown tumor should be considered as a differential diagnosis of mandibular tumors due to the fact that not every tumor has a primary etiology
